a few of the others are still in a transitional stage, changing 
without a moult from red to pure white with black shafts. 
In our young male the tail-feathers are red, changing to 
white, the secondaries being broadly edged with white. In 
the adult female the tail-feathers are uniform red, the 
secondaries being edged with chestnut.

Prahsu and Fumsu. 
Our two female specimens, obtained at Prahsu and 
Fumsu, are much less bright on the upper parts than the 
male ; the crowns are dull velvety black, with little or no 
gloss on the feathers ; the tail-feathers are dirty reddish 
brown. 
In the British Museum there are three specimens of this 
species from Ashanti, which are similar to our female 
examples.
